"AFM is a rare complication primarily affecting children that can occur from not only a variety of viruses, but environmental toxins and genetic disorders as well. Unfortunately, the cause of many cases of AFM is not identified despite extensive testing. CDC has noted an increase in cases since 2014 and has been investigating, but no clear cause of the increase has been identified," states Laura Renwick with SCDHEC.

Despite its similarities to Polio, there's no vaccine available or a specific treatment for the disorder. Long-term outcomes are unknown.

While AFM in itself is not contagious, the CDC recommends washing your hands often with soap and water to avoid getting sick and spreading germs to other people.
